SG input level for 12dB SINAD are obtained measured by connecting SG to each point via a 0.01µF capacitor.

AF VTVM AF level obtained when the AF output level is adjusted for 0.45V/4� with the front panel AF VOL control. Measured with AF voltmeter connected to the external speaker jack, receiving a �53dBm SSG signal modulated at 1kHz, DEV. 3kHz (Wide), 2.4kHz (Semi-wide), 1.5kHz (Narrow).
